Swimming training device

ABSTRACT

A device for improving the swimming performance of a user. The device includes an upper layer made of a translucent or transparent material, a middle layer disposed adjacent the first layer and made of a reflective material, and a lower layer disposed adjacent the second layer. The third layer is made of an opaque material. Additionally, a line is disposed along a length of at least one of the upper, middle, and lower layers to assist the user in determining a position of the user, so as to correct movements of the user.

BACKGROUND

Many devices exist that are directed to the problem of assisting swimmers in improving their performance. Most of these devices include elements which require the strapping of the swimmer's limbs to various moving elements of the apparatus which provides an artificial character to the instruction and forces rather than guiding the swimmer through the proper motions.

One particular device is described in U.S. Pat. No. 4,693,570 (Kryder). The device of Kryder comprises a mirror assembly including two sheets of shatter resistant acrylic plastic having reflective characteristics. The acrylic plastic sheets are held together by a peripheral channel-like framework engaging the exposed edges of the sheet members. The framework includes means for suspending the mirror assembly from a wall or the like. Due to its lightweight construction, the mirror assembly of Kryder is portable and easily positioned for use without requiring special mounting equipment. For example, the mirror assembly may be hung on a wall suspended from a rope or wire having the ends thereof extending through channel in the fashion of a picture or the like. Nevertheless, the device of U.S. Pat. No. 4,693,570 is devised to be applied or used in various sports, so it is limited when considering extra elements that might assist in a specific sport, such as swimming.

SUMMARY OF THE INVENTION

The embodiments discussed herein relate to a device for assisting a user (e.g. a swimmer) in training or performing an activity inside a swimming pool.

In one embodiment, the device includes a reflective surface and marks which allow the user to follow his body movements for improving his performance.

In another embodiment, the device further includes luminous means which permits the user to follow his body movements for improving his performance

DETAILED DESCRIPTION OF THE INVENTION

The device 1 shown in FIGS. 1 and 2 includes a body including three layers piled one over the other. In FIG. 1 one embodiment of the device is depicted to show the main elements defining the same. The device 1 comprises three layers. The upper layer 2 is a clear sheet made of a translucent or transparent material. The material could be made of a polymer, such as plastics, acrylics, polycarbonates, etc., metallic materials, carbon fiber, fiberglass, and in general, composite materials. The material of layer 2 is resistant to breakage and it allows for detailing marks or elements thereon, or in the layer 3 just below layer 2. Layer 2 may include one or more additional elements such as lines, angles, and shapes in order to assist the swimmer to improve his performance. The device of FIG. 1 comprises a line 5 covering part of the surface of layer 2. More preferably, line 5 goes from one end to the other of the device 1 to cover the whole length of layer 2. Line 5 is placed near the center of layer 2. Line 5 allows the swimmer to check the changes in his body position during a swimming activity and to thereby be able to correct it. The swimmer must avoid crossing line 5 so he can keep his body aligned and move faster with less effort. Line 5 is particularly helpful for improving freestyle and butterfly swimming techniques. Layer 2 may also include marks 8 along with line 5, or the marks 8 may be alone without line 5. Marks 8 may include numbers, letters, symbols, geometric shapes, or similar characters and may be placed along the surface of layer 2, assisting the swimmer to assess his movements, especially the strokes. The number, shape, size, position, and distance between marks 8 may change according to the user or exercise. Line 5 and marks 8 may be printed on the surface of layer 2, may be placed or printed inside the body of layer 2, or may be made of a material that can be stuck onto and removed from layer 2 in order to reposition the line 5 or the marks 8 according to convenience of the user or swimmer. Additionally, layer 2 may include weights 7 to prevent the device 1 from moving along the bottom of the swimming pool and thus, changing the “right” path to be followed by the user or swimmer.

The second or middle layer 3 is a reflective sheet made of a mirror-like material of varying intensities, from clear glass to darker shades, but always allowing the swimmer to see his own reflection. Layer 3 is placed below layer 2 in facing contact with layer 2, as shown in FIG. 2. Layers 2 and 3 may be joined together to each other by glue, means of acrylic cement, polymeric adhesive, or any suitable means that doesn't radically hinder the swimmer from seeing his own reflection.

The lower and third layer 4 may be an opaque sheet or material. The material may be made of a polymer, such as plastics, acrylics, polycarbonates, etc., metallic materials, carbon fiber, fiberglass, and in general, composite materials. Layer 4 is placed below layer 3 in facing contact with layer 3, as shown in FIG. 2. Layers 3 and 4 are joined together to each other by glue, means of acrylic cement, polymeric adhesive, or any suitable means. The layer 4 is usually in direct contact with the bottom of the swimming pool, however, layer 4 may include suitable means 6 for sticking up from or being fastened to the bottom of the swimming pool. The means 6 can be double-side tape, hooks, VELCRO® system, or similar means. Additionally, layer 4 might include weights similar to weights 7 shown in FIG. 1 to prevent the device 1 from moving along the bottom of the swimming pool and thus, changing the “right” path to be followed by the user or swimmer. In a special embodiment, means 6 and weights are the same element. In another possible embodiment, weights 7 are attached to the sides of the device 1 so they do not hinder the user from seeing his own reflection.

It is noted that all layers of the device are made of a material resistant to breaking or other deterioration induced by submersion in water.

In an alternative embodiment, the device may include fewer than three layers. For example, the line and/or marks may be incorporated in a single layer having at least one reflective surface. Or, a double-layered device may include the lines and/or marks in an upper layer disposed on a lower layer, and either layer may have a reflective surface or coating thereon.

In FIG. 5, a preferred embodiment of the device is shown, in which line 5, as disclosed herein, has been replaced by a lighting system. More preferably, the lighting system is an LED lighting system 5′, which indicates a speed to the user, as the lights move along the piece continuously at a preset rate. This embodiment is also shown in FIG. 6 where the LED lighting system 5′ is depicted as a discontinuous line of star-like luminous elements. Each LED of the LED lighting system 5′ is operated independently, so as to display as a continuous water drop effect at a predetermined speed, and the speed can be set according to the user's needs or interests via a speed controller such as an RGB speed controller. LED lighting system 5′ can be set on the surface of layer 2. More preferably, LED lighting system 5′ is set inside the body of layer 2, and most preferably, inside the body of layer 2 and in direct contact with layer 3.

The dimensions of device 1 may be adapted according to the swimming pool or the athlete's requirements. Preferably, the dimensions of the device 1 (Length×Width) are about 2′×0.8′, 2.6′×0.82′, or 3.28′×0.98′, for example. Preferably, the thickness of the device 1 ranges from about 0.2″ to 2″.

In one preferred embodiment, more than one device 1 can be joined to form an arrangement of a multi-piece long line (path) of the desired length as partially shown in FIGS. 3, 4, and 6. In this embodiment, multiple devices 1 are joined together by appropriate means to keep them together, such as magnetic means, hooks, etc. More preferably, the multiple devices 1 are joined by one or more VELCRO® fasteners.

It will be clear that while the forms of the invention disclosed herein are intended to fulfill the requirement of clearness and sufficiency, the invention is susceptible of embodiments in various other forms.
